Key Features
FPR4115-NGFW-K9 is the Cisco-listed NGFW appliance PID for Firepower 4115, so the order should match a Threat Defense deployment rather than an ASA appliance record.
The 4115 row sits above the 4112 row with 80 Gbps firewall summary performance and 33 Gbps NGFW and IPS summary figures, giving buyers a clear model-tier reason to stay with this SKU.
Eight on-chassis 10G SFP+ data ports form the base connectivity set, and the two network module bays are reserved for Cisco-listed 1G, 10G, 40G, 100G, or fail-to-wire expansion modules.
Cisco lists the 4115 with 192 GB memory and 400 GB storage, which keeps it above 4112 memory scale but below the 800 GB storage profile of the 4125 and 4145 appliances.
Cisco compatibility documentation ties Firepower 4115 software planning to supported Threat Defense and FXOS combinations, so the software target should be checked before the appliance is quoted.
The hardware guide lists field-replaceable power supplies, fan modules, SSD, network modules, rack hardware, and power cords, which keeps installation parts visible in the procurement review.
Application Scenarios
Choose FPR4115-NGFW-K9 when the approved firewall design names a Firepower 4115 NGFW appliance and the sizing file points to the 33 Gbps Threat Defense table row.
Use the NGFW PID when asset records, support entitlement, and the deployment plan need Threat Defense alignment; the ASA PID is a different orderable identity even when the 4115 chassis class is shared.
Select this appliance for a rack plan that starts with eight fixed 10G SFP+ interfaces and needs two Firepower 4100 network module bays for approved I/O expansion.

- In a FPR4115-NGFW-K9 vs FPR4115-ASA-K9 comparison, the hardware model, memory, storage, ports, and power options match, but the Cisco PID description separates the NGFW appliance from the ASA appliance.
- The FPR4115-NGFW-K9 difference from FPR4112-NGFW-K9 is the model tier: FPR4115-NGFW-K9 uses the 4115 row with 80G firewall and 33G NGFW summary figures, while FPR4112-NGFW-K9 uses the 4112 row with 40G firewall and 19G NGFW summary figures.
- For FPR4115-NGFW-K9 vs FPR4125-NGFW-K9, both are NGFW appliances in the Firepower 4100 Series, but FPR4125-NGFW-K9 moves to 45G NGFW, 25 million concurrent sessions, 800 GB storage, and dual 1100W AC power.
- Buyers deciding which model to choose should order FPR4115-NGFW-K9 only when the BOM requires the Firepower 4115 NGFW appliance identity and the 4115 performance and storage profile match the approved design.
Selection Guide
1. Start with the orderable software role
Select FPR4115-NGFW-K9 when the firewall BOM names a Cisco Firepower 4115 NGFW appliance for a Threat Defense deployment.
2. Keep the ASA PID out of NGFW quotes
Use FPR4115-ASA-K9 only when the design calls for the ASA appliance identity; the two SKUs share the 4115 hardware class but do not represent the same orderable role.
3. Confirm that the 4115 tier is enough
Stay with FPR4115-NGFW-K9 when 33 Gbps FW + AVC throughput, 33 Gbps FW + AVC + IPS throughput, and 15 million AVC sessions fit the sizing plan.
4. Move up only for documented 4125 requirements
Compare FPR4125-NGFW-K9 if the project needs 45G NGFW performance, 25 million sessions, 800 GB storage, or the dual 1100W AC power profile listed for the 4125.
